 In this double exposure, a female firefly (foreground) responds to a nearby male flashing in the grass. Fireflies communicate through light, using species-specific flash patterns to attract mates during the summer. The male and female continue a “flash dialogue,” a call-and-response pattern, until the male finds her in the dark. (Photos by Anna Miller/Animalia Podcast) Fireflies aren’t all sweetness and light…they also have a dark side too! Renowned firefly researcher Sara Lewis and PhD student Avalon Owens discuss all things lightning bugs, including surprising backstories of predation, toxins, and deception. Turns out, there’s a lot more going on in our backyards than we think! A meadow bursts with light nearly two hours after sunset, with each firefly species emitting its unique flash pattern. Fireflies only fly around and flash to find mates for a brief two-week period, before they mate, lay eggs and then die.  A firefly spends the majority of its life – roughly two years – underground as tiny larvae (as seen under a microscope). Firefly larvae are predatory, and some species specialize in devouring earthworms. Tufts PhD student Avalon Owens brings a firefly pupa out in the lab. Even at a young age, a firefly is able to glow, signaling its toxicity to predators. Research assistant Francisca Donkor (left), PhD student Avalon Owens and research assistant Vaidehi Chotai, share a laugh after setting up equipment at their field site on a wooded trail in Concord, Mass. The team is testing whether light pollution and specific colors of light impact firefly courtship and preferences. Research assistant Oliver Nguyen (left) shines some light on Avalon Owens as she holds a male firefly in the palm of her hand at their research site in the woods of Concord, Mass. The team conducts their research entirely in the dark, and only turn on their red headlamps at the end of the evening, once all of the data has been collected. 

Think all bees are the same? Think again! This episode, we dive in to the world of native bees with bee expert Nick Dorian - and find out which bees are the rock-star pollinators, which ones sting, which bees produce the worst honey he’s ever tasted, and why native bees might be the future of how we farm.

For nearly fifty years, Project Puffin has been working nonstop to bring Atlantic Puffins back to a remote island off the coast of Maine. This episode, we touch down in one of the few Atlantic Puffin colonies in all of the United States, and meet the man behind the puffin resurgence. 

Every spring, frogs, salamanders and toads migrate throughout New England. During the trek, they often cross busy highways and roads – and many won’t survive the journey. This episode, we’re touching down in Keene, NH, to witness a migration and meet a group of volunteers who are helping local amphibians to beat the odds.
